We wanted to invent something that would let people with smart glasses enjoy vision that was pleasant, glare-free and better than ever before. Something that would let them clearly recognize superimposed information at any time, regardless of the type of background.

Our patented Active Anti-Glare technology has succeeded at this. We have invented the first application ever that can react to the environment just as wearers require. The only glasses that actively use biofeedback. Of course this also makes inflexible, whole-surface darkening a thing of the past.

One idea – three functions

The core of the innovation is an ongoing adjustment of the strength and area of partial darkening in relation to the opening of the pupils, as well as the inclusion of biometric data from the eye.

1. Variable shading through biofeedback in real time
The more tired you are, the more light-sensitive your eyes become. The lighter it is, the more your pupils contract.When it is dark, your eyes open wide. AAG are intelligent eye-tracking glasses that track your pupil. The biofeedback from the pupil is used to control the level of the shading in real time. AAG achieves this by measuring the variable diameter of the pupil.

2. You can see the eyes of the person you are talking to

You want to look into each other’s eyes. That is why the normal state of really intelligent smart glasses should not already be dark. Active Anti-Glare Glasses are dynamic sunglasses that shade the eye only in the exact areas needed. They also continuously adjust the intensity of the darkening to changing light conditions and the wearer's permanently changing needs. The result is similar to high-dynamic-range imaging but applied directly to the perceived image.

3. Darkening for information displays

To make information uniformly legible against backgrounds with different levels of brightness, high-quality data glasses need the option of partial shading. AR glasses, however, can only display additional light. The AAG technology can darken optimally selected areas behind the displays. This makes the content more legible.

In see-through augmented reality glasses, this technique can also be used to guide the direction of view. Part of the perceived image can be made slightly darker. This makes the rest slightly brighter. With changed intensities of brightness, user attention can be guided for many apps like navigation, tourism, highlighting dangerous objects, and much more.

Easy to build
It is easy to integrate AAG technology into data glasses. The diameter of the pupil is read continuously by cameras directed at the eyes. This information is compared to that of the camera directed towards the line of sight. An LCD layer in the glass ensures the ongoing partial darkening of lighter areas, which compensates for glare and increases the contrast for displays.

Active Anti-Glare is the only non-distracting app for augmented reality glasses. All other AR-apps put some information into the field of view which potentially can draw attention from the real world. Active Anti-Glare Glasses however, remove irritating glare spots and glare fields.

AAG technology is a unique selling point for the future of data and AR glasses. And a real killer application.

In the next step of binocular augmented reality glasses, eye tracking will be included. With such higher developed augmented reality glasses Anti-Glare functionality can share all of its hardware.

With this synergy they can promote each other. AAG is a unique feature that can’t be bypassed or imitated. This is the feature that will influence the buying decisions. AAG is a major strategic advantage for the entire era of smart glasses.

AAG technology is patent protected

We are proud that according to rule 71 (3) EPC the European Patent Office announced its intention to grant the patent under patent no. EP2923234!

The international patent is filed under patent no. WO2014079574. Both have the title "Method for reducing the light intensity of at least one object perceivable by a spectacle wearer and anti-glare spectacles".
